Explanation:

a disaccharide composed of glucose and fructose; sometimes known as table, beet, or cane sugar and, often, as simply sugar. polysaccharides another term for complex carbohydrates; compounds composed of long strands of glucose units linked together (also called complex carbohydrates).

Owing to the fact that the parent cell duplicates itself with the same number of chromosomes into the daughter cells then the daughter cell each have eight chromosomes.

The term cell division has to do with the process by which a cell is broken down to give daughter cells. The process of cell division is responsible for the growth of the organisms. There are two kinds of cell division and these are the mitosis and the meiosis.

While mitosis occurs in the body cells, meiosis occurs in the gamete cells of the organisms. We know that in mitosis, the cell duplicates the exact same number of chromosomes in the parent nucleus into the daughter nucleus hence the daughter nuclei both have eight chromosomes.

Crosscutting Concept: Patterns

Patterns observed in the natural world facilitate organization and classification, as well as raise inquiries about the underlying relationships and causes.

During my exploration of energy usage in residential settings, I discerned several discernible patterns. For instance, a prominent pattern emerged, indicating that the bulk of energy consumption in homes pertains to heating and cooling, followed by lighting and appliances. Moreover, I discovered that energy usage displays notable variations based on factors such as dwelling size, number of occupants, and climatic conditions.

These identifiable patterns enable us to comprehend the factors influencing energy consumption and identify avenues for conservation. By acknowledging that heating and cooling dominate energy use, we can channel our efforts towards enhancing the efficiency of these systems.

Utilizing empirical evidence, claims can differentiate between causal relationships and mere correlations, thus supporting the establishment of specific cause and effect linkages.

During my investigation into energy usage in residential environments, I employed empirical evidence to unveil distinct cause and effect associations. For instance, I observed a positive correlation between energy consumption and dwelling size. This relationship can be attributed to the increased energy requirements for heating and cooling in larger homes.

Similarly, I discovered that energy consumption rises alongside the number of occupants. This phenomenon arises due to the presence of more individuals utilizing appliances and lighting fixtures.

These cause and effect relationships foster a deeper comprehension of how our choices impact energy consumption. For instance, if we aspire to curtail our energy usage, we can opt for smaller homes or limit the number of occupants.

Crosscutting Concept: Stability and Change

Analysis and explication of geoscience data and global climate models reveal that modifications within one Earth system can yield feedback loops, which can either stabilize or destabilize the system.

Throughout my examination of energy usage in residential settings, I ascertained that alterations in a single energy-consuming appliance or behavior can trigger a chain reaction affecting other appliances and behaviors. Consider replacing inefficient light bulbs with energy-efficient alternatives; this simple change can prompt a behavioral shift to turn off lights when leaving a room, subsequently resulting in a substantial reduction in energy consumption.

These feedback loops empower us to comprehend how our choices can influence the environment. For instance, collectively opting for reduced driving can mitigate air pollution and greenhouse gas emissions.

By comprehending the crosscutting concepts of patterns, cause and effect, and stability and change, we can make informed decisions regarding energy usage. These choices enable us to diminish our environmental footprint and forge a sustainable future.

Air masses get from one place to another through evaporation

What locations do evaporation and transpiration occur in?

Water that evaporates into the atmosphere from the soil surface, the groundwater table's capillary edge, and land-based bodies of water is referred to as evapotranspiration. Transpiration, or the transfer of water via plants from the soil to the atmosphere, is also a component of evapotranspiration.

Water on the surface of the earth enters the soil through a process called infiltration. The rate at which soil can absorb rain or irrigation is known as infiltration rate in soil science. It is expressed in millimeters per hour or inches per hour. As the soil becomes saturated, the rate slows.

Answer:

carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day.

At first, scientists thought that this might be a good thing because it leaves less carbon dioxide in the air to warm the planet. But in the past decade, they’ve realized that this slowed warming has come at the cost of changing the ocean’s chemistry. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic—faster than any known change in ocean chemistry in the last 50 million years.

Scientists formerly didn’t worry about this process because they always assumed that rivers carried enough dissolved chemicals from rocks to the ocean to keep the ocean’s pH stable. (Scientists call this stabilizing effect “buffering.”) But so much carbon dioxide is dissolving into the ocean so quickly that this natural buffering hasn’t been able to keep up, resulting in relatively rapidly dropping pH in surface waters. As those surface layers gradually mix into deep water, the entire ocean is affected.

Such a relatively quick change in ocean chemistry doesn’t give marine life, which evolved over millions of years in an ocean with a generally stable pH, much time to adapt. In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification may affect ocean life. Overall, it's expected to have dramatic and mostly negative impacts on ocean ecosystems—although some species (especially those that live in estuaries) are finding ways to adapt to the changing conditions.

However, while the chemistry is predictable, the details of the biological impacts are not. Although scientists have been tracking ocean pH for more than 30 years, biological studies really only started in 2003, when the rapid shift caught their attention and the term "ocean acidification" was first coined. What we do know is that things are going to look different, and we can't predict in any detail how they will look. Some organisms will survive or even thrive under the more acidic conditions while others will struggle to adapt, and may even go extinct. Beyond lost biodiversity, acidification will affect fisheries and aquaculture, threatening food security for millions of people, as well as tourism and other sea-related economies.

Answer:

What is a macrocolecule?

A biological macromolecule is a very large molecule that is built from smaller biological, or organic, molecules that are linked together by covalent bonds.

Macromolecules are necessary for an organism’s growth and survival

There are four major classes of biological macromolecules. Carbohydrates, Proteins, Fats, and Nucleic acids (DNA and RNA)

What do you notice about the atoms that make up these molecules?

Carbs-They contain carbon, hydrogen, and oxygen and include the sugars, starches, and fibers that are found in grains, fruits, and vegetables.

Carbohydrates are important for brain function, and they provide energy for working muscles and the central nervous system.

Protein- This type of macromolecule can be found in meats, poultry, fish, eggs, dairy products, nuts, and legumes.

Protein is necessary for building and repairing muscle mass, and it helps maintain a healthy immune system.

There are about 20 amino acids,most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.

Fats-are used by the body as energy and to store fat-soluble vitamins (vitamins A, D, E and K). They also insulate the body and protect vital organs.

The human body stores excess fat in specialized cells called adipocytes.

consists of two main components—glycerol and fatty acids.

What happens to macromolecules from food during digestion?

Glycolysis can be best explained as a series of chemical reactions that extract energy from glucose. This process occurs in liver cells. At the start of glycolysis, a molecule of glucose (C6H12O6) is trapped and destabilized, or broken down into two three-carbon molecules. These molecules are called pyruvate. The net products of the process are two molecules of ATP—four molecules of ATP are actually produced, but two are used up—and two molecules of NADH. The liver also metabolizes other macromolecules,

If there is not enough carbohydrate intake, how does the body form glucose?

When there is a shortage of fats or carbohydrates, proteins can also yield energy.

Fats typically provide more than half of the body's energy needs.

If not enough protein is provided by the diet, the body starts chewing on muscle cells.

If there is a glucose shortage, how does the body produce energy?

glucose can be made in the liver and kidneys using protein from elsewhere in the body.

What atoms make up sugar molecules, amino acids, and fatty acids?

Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat
